Skin cancer can occur in many forms. There are over 1 million cases of skin cancer that occur every year in the United States alone. Also, patients with a history of sunburns, tanning, lots of moles, and a family history of skin cancer are at higher risk of developing such spots. The three most common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. The most important thing about skin cancers is early detection and treatment so that we can achieve the highest rates of cure. Melanoma is the most serious form of skin cancer and regular skin exams at home and annual exams with your dermatologist can help with early detection.
